The paraconal interventricular branch of the left coronary artery
What is the difference in the subsinuosal interventricular branch between the dog and the cat?
In the dog, the subsinuosal interventricular branch is a continuation of the circumflex branch of the left coronary artery while it could also be from the right coronary artery in the cat.
